The AGC will not cause "hard limiting" - in other words, it should
maintain linearity.
Even though the strongest signal in the passband will control how much
AGC is applied, weaker signals in the passband should sound
proportionally weaker.
Now that you mention hard limiting, there is a limiter in the K3 that if
turned on will protect your ears. I am wondering if some instances of
reported receiver mush did have limiting set on - that would be
particularly true for those who chose to ride the RF Gain and/or run
with AGC off.

Hi,
Where in Smith's article does it say that AGC with the slope set for 15 acts
as a hard limiter? There is a huge difference between AGC action (which is
simply a reduction in gain with linearity retained) and hard limiting.
